摘要
介绍了真空技术在污水处理中的几种典型应用 :真空结晶法用以分离污水中具有结晶性能的固体溶剂 ;真空过滤脱水用于初沉池和消化池污泥脱水 ;真空浮选法通过制造负压条件加速浮选过程 ;还有真空搅拌、真空脱气等等。
This paper introduces several exponent applications of the vacuum technology in the process of the wastewater treatment. The crystal way in vacuum is to apart the solid solvent which has crystal capability in wastewater. Sludge dewatering of vacuum filtration is mainly applied to dehydrate the sludge in primary setting tank and digestion tank. Vacuum air floatation is to accelerate air floatation by making vacuum condition. And there are many other applications such as agitation in vacuum, degassing in vacuum and so on. All of these are enough to explain that vacuum technology is important in wastewater treatment and even if in environment protection.
